Discussion

A new music sequence has only a tempo track, with a default tempo of 120 beats-per-minute. The default sequence type is beat-based. For the various sequence types, see MusicSequenceType.

To direct the output of a music sequence to an audio processing graph, use the MusicSequenceSetAUGraph(_:_:) function. To direct the output instead to a MIDI endpoint, use the MusicSequenceSetMIDIEndpoint(_:_:) function.

To direct the output of a specific music track, use the MusicTrackSetDestNode(_:_:) and MusicTrackSetDestMIDIEndpoint(_:_:) functions, described in MusicTrack.
